The thesis is focused on diets prescribed to patients in the spa resorts. The selected spa resorts are Lazne Luhacovice, Lazne Teplice nad Becvou and Marianske Lazne. Three types of diets such as low cholesterol, reducing, diabetic, and their standards of nutritional factors are described. The thesis also deals with the evaluation of menus compiled in ac-cordance with selected diets, that are created by nutritional therapists of spa facilities. Eva-luation is made on the basis of values of selected nutritional factors. It was found that the performance values of most of the monitored factors were within their normal limits, and it indicates that conditions of selected diets are not complied. The final results show that any of the selected spa facilities is satisfactory.
